Answers and Explanations

1. He’s the one which who/that has the blue tie on.

We use the relative pronoun which to refer to things. To refer to people, we use who or that. In formal writing, who is a better choice.

Examples:
He was the one who/that recommended this solution.
He was the one which recommended this solution.

 

2. We like very much the new secretary very much.

We don’t normally place an adverb between a verb and its object.

Examples:
I like sports a lot.
I like a lot sports. 
The doctor patiently described the surgical procedure.
The doctor described patiently the surgical procedure.

 

3. Could you tell me how can I I can get in touch with Mr. Yamamoto?

After expressions like Do you know…Could you tell me,.. and I was wondering if… we do not invert the subject and the verb. These are called indirect questions.

Examples:
I was wondering if you could help me with something.
I was wondering if could you help me with something. 
Could you tell me how I should do this?
Could you tell me how should I do this?

 

4. We’re not sure he is enough experienced experienced enough for the position.

Enough goes after an adjective or before a noun.

Examples:
Do we have enough food?
Do we have food enough?
Is the conference room big enough for 10 people?
Is the conference room enough big for 10 people?

 

5. She’s very sick and has been at in the hospital for two weeks.

To communicate that someone is a patient at the hospital, we say in the hospital. If someone is not a patient, we use at the hospital.

Examples:
The surgery went well. She was only in the hospital for two days.
The surgery went well. She was only at the hospital for two days.
I think Stephanie’s at the hospital visiting her great aunt.
I think Stephanie’s in the hospital visiting her great aunt.

 

6. We talked during for three hours this morning.

We use for to communicate a duration a time. We use during to communicate over what period of time something happened.

Examples:
I slept for three hours, and I woke up just in time for dinner.
I slept during three hours, and I woke up just in time for dinner.
No one interrupted during his presentation.
No one interrupted for his presentation.

 

7. We’re using all the informations we have to make an informed decision.

Information is a non-count noun. There is no plural form of information. Other non-count nouns students frequently misuse include evidenceadvice, stuff, and furniture. There is no plural form of these words.

 

8. They often change often our seats at work.

We put adverbs of frequency (always, usually, never, etc.) before the main verb or after the verb to be.

Examples:
Mike never talks about his ex-wife.
Mike talks never about his ex-wife
Mike talks about his ex-wife never.

 

9. They don’t let us to send our clients gifts without getting approval from management first.

After lethelpmake, and have (when have communicates that someone is being told to do something), we use the base infinitive of the second verb, not the infinitive form.

Examples:
He had his secretary reserve a table for two.
He had his secretary to reserve a table for two.
They made us feel welcome.
They made us to feel welcome.
My niece helped me set up my computer.
My niece helped me to set up my computer.

 

10. Do we have some any coffee or tea to offer our guests?

In general, we use some with affirmative statements and any with questions and negative statements.

Examples:
We’ve had some difficulty getting approval.
We’ve had any difficulty getting approval.
Have you had any difficulty getting approval?
Have you had some difficulty getting approval?
We didn’t have any difficulty getting approval.
We didn’t have some difficulty getting approval.

11. I called Kate this morning and she told me she’ll she would (or she’d) call me back in a half an hour.

When reporting what someone said, will becomes would and won’t becomes wouldn’t. We can leave it as will if it’s something that is still going to take place in the future.

Examples:
Before the election, both candidates promised they wouldn’t raise taxes.
Before the election, both candidates promised they won’t raise taxes.
The meeting went well. Mike said he would consider our proposal.
The meeting went well. Mike said he will consider our proposal. 

Note that They said they will consider our proposal would be correct if the meeting ended very recently and Mike still hasn’t considered the proposal.

 

12. We regularly conduct emergency drills for ensuring to ensure that we are prepared for an emergency.

To describe the purpose of something, we can use the gerund. To describe the purpose of someone, we use the infinitive. This page does an excellent job describing the difference.

 

13. Brad is 32 now. He completes turns 33 years in October.

To communicate the someone is becoming a year older, we use turn, not complete. Also, we do not say years after the number unless we say years old.

Examples:
I can’t believe my youngest sister is turning 20 this year.
I can’t believe my youngest sister is completing 20 this year.
Let’s have a big party when you turn 40.
Let’s have a big party when you turn 40 years.

See these collocations exercises to practice using correct word partners.

 

14. These are the most cheap cheapest gas prices I have seen in my life.

To form the superlative form of most one-syllable adjectives, we add “est” to the end of the word.

Examples:
Are you sure this is the newest release?
Are you sure this is the most new release?
Kevin is the oldest person here.
Kevin is the most old person here.

 

15. Yesterday, I must sent had to send a very important email to a client.

We don’t use must to communicate a past obligation or necessity. Instead, we use had or needed.

Examples:
To travel to Indonesia, I had to get a visa.
To travel to Indonesia, I must got a visa.
Marilyn will be right back. She needed to take an important call.
Marilyn will be right back. She must took an important call.

 

16. We knew there was a gas leak because it smelled really badly bad inside the house.

We use bad, not badly to modify states of being (look, smell, taste, feel, etc.). Similarly, we use good, not well to modify states of being.

Examples:
This coffee tastes bad.
This coffee tastes badly.
Do you think the decorations look good?
Do you think the decorations look well?

 

17. My parents always told me that it’s important being to be positive.

The correct form is It’s + adjective + infinitive. We can add for + object before the infinitive.

Examples:
It’s impossible for us to complete this on time.
It’s impossible for us completing this one time.

 

18. For Because of/Due to the economy, we haven’t been able to hire any new people.

To introduce a reason, we typically use because of or due to, not forBoth because of and due to must be followed by a noun or a gerund.

Examples:
Because of its negative side effects, the medication was banned.
For its negative side effects, the medication was banned.
I was late because of the traffic.
I was late for the traffic.

 

19. He says that he’s been really tired since several weeks ago for the last several weeks.

We use since with a point in time (9 AM, Tuesday, 1994, etc.). We use for to talk about a duration of time (three days, 12 seconds, two months, five years, etc.).

Examples:
They’ve been in the lobby for two hours.
They’ve been in the lobby since two hours.
They’ve been in the lobby since 10 AM.
They’ve been in the lobby for 10 AM.

 

20. A friend of us ours is going to pick us up at the airport.

We use the possessive pronouns mine, yours, his, hers, theirs, and ours in these type of statements. If we are using someone’s name, we use the possessive (Brad’s, Kate’s Leonard’s, etc.).

Examples:
I saw a friend of yours last night at the party.
I saw a friend of your last night at the party.
Didn’t you say that a friend of Mike’s works at the post office?
Didn’t you say that a friend of Mike works for at post office?

 

21. I’ve worked like as a waiter in the past, but I wouldn’t want to do it again.

We say someone works as + occupation to communicate what someone’s job is.

Examples:
He used to be a full-time employee, but now he’s working as a consultant.
He used to be a full-time employee, but now he’s working like a consultant.

 

22. To sleep Sleeping at work is acceptable in some cultures.

When the name of an activity is the subject or object, we normally use the gerund.

Examples:
Fishing is a good way to relax.
To fish is a good way to relax.
My job involves writing technical documents.
My job involves to write technical documents. 

 

23. Because of these problems (or Due to these problems), we shouldn’t move forward with this proposal right now.

Because of and due to are followed by a noun or gerund. Because is followed by a subject and a verb.

Examples:
I was late because of the traffic.
I was late because the traffic.
I was late because there was a lot of traffic.
I was late because of there was a lot of traffic.

 

24. I’m going to take my lunch break and then to make some phone calls.

If we use two different verbs after going to, we do not use the infinitive form of the second verb. Instead, we use the base infinitive (infinitive without to).

Examples:
Management is going to look at the bids and decide on a vendor.
Management is going to look at the bids and to decide on a vendor.
Monica told me she was going to stop at the bank and deposit the money.
Monica told me she was going to stop at the bank and to deposit the money.

 

25. I’ve asked everyone to help me with my college admissions essay. Even I I even asked someone I met on the bus.

We can use even to emphasize something surprising or extreme. The correct form is subject + even + verb.

Examples:
I’ve looked everywhere for my keys. I’ve even looked in the refrigerator!
I’ve looked everywhere for my keys. Even I’ve looked in the refrigerator!
They said they’re doing everything they can to save money. They even sold their car.
